Answer:
The second one is the largest area
Step-by-step explanation:
3/2 is greater than all of the other widths so the second towel has the greatest area.
4^9 is the correct answer to your question
We can divide this figure into triangle and trapezoid.
Area of a trapezoid = (1/2)*(base1 +base2)*height = (1/2)(11.75+18)*6.12 = 91.035
Area of a triangle = (1/2)*base*height=(1/2)*12*13.42 = 80.52
Area of the whole figure = 91.035 + 80.52 = 171.555
Answer:
Step-by-step explanation:
The motorist drove at a distance of 90km at a constant speed for the first 40km, and then 20 km/hr faster for the rest of the journey.
The whole journey took him 1hr.
Let S denotes the average speed (in km/hr) for the first 40 km.
Hence we get the following relation,
40/S + (90 - 40)/(S + 20) = 1
or 50/(S + 20) = 1 - 40/S = (S - 40)/S
or (S + 20)(S - 40) = 50S or S^2 - 70S - 800 = 0 or (S - 80)(S + 10) = 0
or S = 80 (km/hr) [Ans]
[S cannot be negative value]
